A system for acquisition, processing and display of gated SPECT imaging data for use in diagnosing Coronary Artery Disease (CAD) in nuclear medicine. The present invention provides a physician with two parameters for evaluating CAD: information relating to the distribution of blood flow within the myocardium (perfusion) and information relating to myocardium wall motion (function). One aspect of the present invention provides the physician with a display of functional images representing quantitative information relating to both perfusion and function with respect to selected regions of interest of the subject heart at end-diastole and end-systole segments of the cardiac cycle. The functional display consists of arcs of varied width depending on wall motion and color coded to illustrate degrees of myocardial perfusion for different pie shaped sections of a selected region of interest within a given short axis slice of reconstructed volume data. The present invention also provides a series of display images allowing facilitated access, display, and comparison of the numerous image frames of the heart that may be collected during gated SPECT sessions. The present invention also offers the ability to define and recall parameter files representative of data acquisition and processing parameters and protocol for use in gated SPECT studies. The invention also includes a semi-list processing mode to increased efficiency of data acquisition within a camera computer system.

Method and apparatus for information acquistion, processing, and display

A forming wheel carriage for a CNC controlled metal spinning machine having a forming wheel post arranged to be movable relative to a second slide, and a process for operation of the metal spinning machine. During operation the forming wheel post is attached relative to the second slide by means of a ball flexibly mounted on the second slide engaged into a recess of the forming wheel post. The ball deflects backwards during overload, and the forming wheel with the forming wheel post can deflect immediately relative to the second slide. The forming wheel post deflects within a horizontal plane in accordance with a pre-selected force independent of the direction of the overload force. The force can be changed during an overload at a relief valve by means of a control unit by way of a control line. This manner of attachment of the forming wheel post allows for an automatic registering of the spindle tool contour. The contour is recorded point by point. This entails the repeated passage of the wheel with minimal push against the spindle tool. In addition, the positioning means serves as an overload check and emergency shut off switch.

An animated novelty device which is shaped in the form of an animated creature having a flexible body portion and a head portion having eyes. The eyes include a light source connected in a circuit which is operatively associated with a sound producing device which is located within the body portion of the animated device. The arrangement is such that when a force or pressure is applied to the body portion of the device, a sound or voice associated with the animated creature is sounded and simultaneously therewith the eyes light up.
